IMPROVEMENT IN TOOL-RECEPTACLES FOR METAL-WORKING MACHINES.

Specification forming part of Letters Patent No. 164,561, dated June 15,1875 application filed March 2, 1875.

To all whom it may concern Be it known that I, WILLIAM H. HOFFMAN, ofPassaic, in the State of New Jersey, have invented certain new anduseful Improvements in Combined Tool-Closets and Machine-SupportingStructures, of which the following is a specification:

Supports for enginelathes and other machinery have heretofore beenconstructed so as to constitute closets for containing tools and otherdevices used in connection with the machinery. Such combined supportsand closets have been made hitherto in one of two ways that is to say,either with close and imperforate sides,which exclude the light andrender it diflicult for the workman to lay his hand on the tool wanted,or with lattice or open-work sides, as shown in Letters PatentNo.156,745. In either case, however, there has been used a hinged andswinging door.

The combined tool-closet and machine-support made in accordance with mypresent invention differs from those heretofore devised, in that thehinged and swinging door is dispensed with. The closet, when closed,presents imperforate sides, which exclude all dust and dirt; and, on theother hand, when opened, admits the light so freely as to remove allobscurity from its interior.

To accomplish these results, I combine, with an outer cylindrical shell,an inner cylindrical shell containing the shelves, the two shells beingformed with openings in their sides, corresponding to each other, andone of the shells being capable of a movement of rotation, under whicharrangement it may be turned so as to bring the opening or openings init into coincidence with the opening or openings in the other shellwhenever access to the shelves is desired.

The manner in which my invention is or may be carried into efiect willbe understood by reference to the accompanying drawing, in which Figure1 is a side elevation of a machineframe embodying my improvements. Fig.2

is a horizontal section through the supports.

The bed A, carried by the support, is in the present instance the bed ofan engine-1athe.

It is upheld by two supports, each of which, while differing somewhat indetails of construction, embodies the same general feature whichconstitutes the gist of my invention. The support on the left of themachine consists of a fixed stationary shell, B, in the side of which,and diametrically opposite each other, are formed openings at a. Withinthe fixed outer shell, which constitutes the support proper of thelathe-bed, is fitted snugly an inner shell, 0, mounted on pintles b b,so as to rotate on a vertical axis, and formed with openings 0 c, whichcorrespond to openings a a in the outer shell. Fixed within the innershell are shelves d d.

By rotating the inner shell its opening can be brought into coincidencewith those in the outer shell, as shown in the drawing, in whichposition access can be had to the closet from either side, and the lightenters from both sides, thus lighting up the interior, and renderin g iteasy for the workman to find the tool he wants.

To close the closet, all that is required is to rotate the inner shelluntil its openings 0 c are carried behind the imperforate walls of theouter shell, at which time the openings at a, in the outer shell will bein like manner closed by the walls of the inner shell. When the partsare in this position the closet will be completely and tightly closed.

In the support shown on the right of the machine the outer shell D,which is fixed and stationary, and constitutes the support proper, is ahalf-cylinder, more or less. The inner revolving shell is ofcorresponding structure, so that its imperforate wall, when brought tothe proper position, will join onto the wall of the outer shell, andcomplete the inclosure. The inner shell E is provided with shelves d, asin the other case.

To open this closet, a half-revolution of the inner shell will exposethe shelves fully and completely, as will be understood without furtherexplanation.

I would here remark that I have described the apparatus as provided withan inner revolving shell; but this arrangement can be reversed that isto say, the inner shell may be fixed, and may constitute the supportproper, in which case the outer shell would of course be arranged torevolve.

Having now described my invention, what I claim, and desire to secure byLetters Patent, is-- A combined machine-support and tool-re ceptacleconsisting of two concentric shells,

one of which is capable of rotation on the common axis ofthe two shells,the said shells being formed with corresponding openings, and the innershell provided with shelves, under the arrangement and for operation asset forth.

In testimony whereof I have hereunto signed my name this 1st day ofMarch, A. D. 1875. WM. H; HOFFMAN. Witnesses:
